The purpose of this thesis is the design and documentation of a functional design concept for Formula Student prototypes. This new concept should combine all aspects of vehicle dynamics from tyre decision & kinematics to brakes, drivetrain, and suspension components. The resulting concept should be ready to be applied as a Formula Student -vehicle with better performance than its predecessor.
The entire process starts out by setting the status of all vehicle dynamics subsections and basing the performance goals on desired competition results. After this, the tyre decision is made based on test machine data and the rest of vehicle dynamics are designed to support the tyre in achieving its maximum performance potential. Kinematics are additionally designed with theory-based focus on vehicle behaviour.
Multiple design approaches to component dimensioning, such as brakes, springs and dampers are used, including hand-calculations and different simulation software. The findings from all approaches are combined to determine the required range of adjustability and the initial setup to begin testing with.
The final concept achieves improvements in almost all performance properties, exceeding the initial goals. Even as these improvements yet remain unvalidated, the margin that the goals are exceeded by gives confidence that the resulting prototype from TFS-G1 will be more competitive than any of its predecessors. Finally, the next steps in improving the functional design concept further are introduced and explained.
